1. Explosion-proof motor
An explosion-proof motor is an electromechanical device that can be used in flammable and explosive environments without producing electrical sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas fields, petrochemical and chemical industries. In addition, they are widely used in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and pharmaceuticals. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors, and other transmission machinery.

2. Ordinary motor
An ordinary motor is an electromagnetic device that converts or transmits electric energy based on the law of electromagnetic induction. It is represented by the letter M (or D in older standards) in an electrical circuit. Its main function is to generate driving torque and serve as a power source for various electrical appliances or mechanical equipment. A generator is represented by the letter G in an electrical circuit. Its main function is to convert mechanical energy into electrical energy. The most common method currently used is to use thermal energy, hydraulic energy, etc. to drive the rotor of the generator to generate electricity.

Explosion-proof motors and ordinary motors have the same rated voltage, rated current, power, and speed markings. The difference is that explosion-proof motors have an explosion-proof mark: Ex.
